Bladeless Drone

The Bladeless Drone solves the three main problems of today’s common drones: air humming, exposed blades and wind. Without exposed rotor blades, it takes advantage of the headwind and forces it through internal ducts to generate a downward flow.

Imagine one flying a common drone in the neighbourhood park, when suddenly, strong wind gusts over. The drone user tries to control the drone but the headwind destabilises it, taking it down, possibly injuring a child. Such accident can easily happen with today’s drones. Therefore, the Bladeless Drone uses technology that makes flying a drone safer. Without rotor blades, it uses adversities like headwind to its favour by regulating its airflow. This stabilises its motors for smoother flying, while converting the wind into a downward flow.

Unlike common drone’s designs, Bladeless Drone is designed to take maximum advantage of aerodynamics by using shapes we find in today’s airplanes and aircrafts. It is not only innovative in terms of functionality, but also beautiful to look at, be it in rest waiting for take-off, or flying high above.

The Bladeless Drone has four bladeless propellers: the main propeller positioned in the centre uses most of the ducted flow to support take-off and landing; and three other propellers define the direction. It also has four main air intake valves to extract moving air when flying. The Bladeless Drone takes the air and accelerates it through internal ducts and blades, forcing it through small vents generating downward flow and hence, lift.

The two front propellers can rotate 20 degrees forward and backwards. The back propeller rotates 20 degrees clockwise and counter clockwise. Each propeller is programmed to work based on the amount of headwind received. At ground level, the propellers work at their maximum, sucking air from the four intake valves and accelerating it to take-off. During flight, depending on the strength of the headwind, the propellers regulate themselves to save energy and work with the induced wind.
